Thanks for this hint, iabbot. While this does help with installing some Unix software, it shouldn't be necessary with streamripper. I've tested the installation on a freashly installed OS X machine with just the Dev Tools installed, and the install compile went perfectly. As per my addendum, I did need to add the /usr/local/bin directory to allow the install.

I can only reccomend that those of you having problems with the compile, make sure that typing "which cc" returns "/usr/bin/cc" . If it doesn't you should re-install the Dev Tools.
